Motion Based Decompositing Video [bibtex file=IrfanEssaWS.bib key=1999-Brostow-MBDV] Abstract We present a method to decompose video sequences into layers that represent the relative depths of complex scenes. Our method combines spatial information with temporal occlusions to determine relative depths of these layers. Spatial information is obtained through edge detection and a customized contour completion algorithm. Activity […]
Irfan A. Essa “Computers Seeing People”, AI Magazine 20(2): Summer 1999, 69-82 Abstract AI researchers are interested in building intelligent machines that can interact with them as they interact with each other. Science fiction writers have given us these goals in the form of HAL in 2001: A Space Odyssey and Commander Data in Star […]

Georgia Institute of Technology Experimental Software Systems: Automated Understanding of Captured Experience The objective of this research is to reduce substantially the human input necessary for creating and accessing large collections of multimedia, particularly multimedia created by […]
Andrew Gardner and Irfan Essa (1997) “Prosody Analysis for Speaker Affect Determination” In Proceedings of Perceptual User Interfaces Workshop (PUI 1997), Banff, Alberta, CANADA, Oct 1997 [PDF][Project Site] Abstract Speech is a complex waveform containing verbal (e.g. phoneme, syllable, and word) and nonverbal (e.g. speaker identity, emotional state, and tone) information. Both the verbal and […]

Daniel Goldman (1997 “Laugh and Your Computer Will Laugh With You, Someday” Jan 7, 1997 Issue, New York Times, Science TimesQuote from the article: “Emotions like fear, sadness and anger each announce themselves through a unique signature of changes in facial muscle, vocal inflection, physiological arousal, and other such cues. Building on techniques of pattern […]
Darrell, T.J.; Essa, I.A.; Pentland, A.P., “Task-specific gesture analysis in real-time using interpolated views” Transactions on Pattern Analysis and Machine Intelligence , vol.18, no.12, pp.1236-1242, Dec 1996 URL: [ieeexplore.ieee.org] [DOI] Abstract Hand and face gestures are modeled using an appearance-based approach in which patterns are represented as a vector of similarity scores to a set […]
